Intrusion Detection Model Based on Incomplete Information Ga me in Wireless Mesh Networks

Wireless Mesh Networks （WMNs） have many applications in homes, schools, enterprises, and public places because of their useful characteristics, such as high bandwidth, high speed, and wide coverage. However, the security of wireless mesh networks is a precondition for practical use. Intrusion detection is pivotal for increasing network security. Considering the energy limitations in wireless mesh networks, we adopt two types of nodes： Heavy Intrusion Detection Node （HIDN） and Light Intrusion Detection Node （LIDN）. To conserve energy, the LIDN detects abnorrml behavior according to probability, while the HIDN, which has sufficient energy, is always operational. In practice, it is very difficult to acquire accurate information regarding attackers. We propose an intrusion detection model based on the incomplete inforrmtion game （ID-IIG）. The ID-IIG utilizes the Harsanyi transformation and Bayesian Nash equilibrium to select the best strategies of defenders, although the exact attack probability is unknown. Thus, it can effectively direct the deployment of defenders. Through experiments, we analyze the perforrmnce of ID-IIG and verify the existence and attainability of the Bayesian Nash equilibrium.

Extension of LCVM-type mixing rule to three-parameter equations of state for vapor-liquid equilibria of mixtures

In this paper, the LCVM mixing rule is extended to the multi-parameter equations of state by combining infi- nite-pressure and zero-pressure mixing rule models. The new LCVM-type mixing rule, coupled with Patel-Teja equation of state (EOS) is applied for vapor-liquid equilibria of different polar and non-polar systems in which the NRTL activity coefficient model is used to calculate the excess Gibbs free energy. The tested results agree well with existing experimental data within a wide range of temperatures and pressures. In comparison with the Van der Waals mixing rule, the new mixing rule gives much better corre- lations for the vapor-liquid equilibria of non-polar and polar systems.

The possible effects on the future management of local Italian authorities following the use of financial derivative instruments

The appeal from municipalities, provinces and regions to financial derivative instruments is tied to the need of overcoming the situations in a state of urgency inherent in a balance. On average, one local Italian authority in twenty has decided to underwrite a derivative product, giving life to a number of contracts that had a value of over 35 billion euro with an average value of 6.5 million for each contract until 2007. The boom of swaps has, since 2000 on, experienced a peak period from 2003 to the end of 2005, in which the Euribor rate touched a very low level, maintained itself for long periods at around 2% and fallen in some cases even under this value. Many of the contracts completed before 2006, which link the debt of local authorities to variable rates, but also many of those completed from 2006 onwards that moved debt onto fixed rate, which are now a source of loss for the balance of local authorities that have underwritten them. In the 2002-2008 period, the number of the stipulation of contracts local authorities reported to the Ministry of Economy and Finance is about 900, corresponding to more or less 150 per year, which affected 18 regions, 44 provinces, 532 municipalities and 4 mountain commtmities, for a total of 594 authorities. Therefore, the local authorities have approached the derivative instruments in an often approximate way without a real awareness, both for the conditions that were being negotiated and the effects that they would have produced in perspective. The purpose of this work is to highlight the consequences of the use of derivative instruments on the future management of local authorities.

Collision Statistics of Driven Polydisperse Granular Gases

We present a dynamical model of two-dimensional polydisperse granular gases with fractal size distribution, in which the disks are subject to inelastic mutual collisions and driven by standard white noise. The inhomogeneity of the disk size distribution can be measured by a fractal dimension df. By Monte Carlo simulations, we have mainly investigated the effect of the inhomogeneity on the statistical properties of the system in the same inelasticity case. Some novel results are found that the average energy of the system decays exponentially with a tendency to achieve a stable asymptotic value, and the system finally reaches a nonequilibrium steady state after a long evolution time. Furthermore, the inhomogeneity has great influence on the steady-state statistical properties. With the increase of the fractal dimension df, the distributions of path lengths and free times between collisions deviate more obviously from expected theoretical forms for elastic spheres and have an overpopulation of short distances and time bins. The collision rate increases with df, but it is independent of time. Meanwhile, the velocity distribution deviates more strongly from the Gaussian one, but does not demonstrate any apparent universal behavior.

发达国家量化宽松政策下我国资本流动及其对人民币汇率影响的研究

发达国家集体量化宽松货币政策的实施在全球范围引发了海量的国际资本流动。本课题以此为背景,通过对发达国家历次量化宽松政策的梳理,并结合大量数据,运用VAR模型研究分析了美国量化宽松货币政策的实施对中国资本流动及人民币汇率的影响。研究结果表明,美国量化宽松政策在短期内对我国资本流动波动影响较大,并对人民币的升值产生了较大压力。但长期内,我国资本流动和人民币兑美元汇率都趋于均衡状态。本课题在分析研究的基础上,提出我国在后QE时代资本跨境流动的应对策略。
